Insycle supports any HubSpot Custom Objects.
You can use all Insycle modules to manage, maintain, and automate data operations with any custom objects, in the same way that Insycle works with standard objects.
Here is a short walk-through.
To add a Custom Object please reach out via chat or firstname.lastname@example.org.
You can use Insycle to add or remove multiple associations between any object (including custom objects and parent/child companies) and select an association label. For example, associate two companies with the same contact, and label one company "primary" and the other company as "agency".
